IMPROVEMENT IN MACHINE S FOR SPINNING'ROPE-YARN, 80C.

Specification forming part of Letters Patent No. 220,876, dated October 21, 1879;

application filed August 24, 1878.

To all whom it may concern Be it known that L OWEN SHEEIIAN, of New Bedford, Bristol county, Massachusetts, have invented certain newand useful Improvements in Machines for Spinning Rope-Yarns, Hemp Twine, and Mai-line, of which the following is a specification. g

Figure 1 is a Side elevation of my invention, and Fig. 2 is an enlarged detail view of the nipping-rolls. a

The object of my invention is to produce a more simple construction, which is less costly, and which will make a better quality of rope-yarn and more of it in a given time than the machines as will be more fully described now in use,

D represents a suitable frame, in the lower part of which is journaled the Shaft it, having the beveled wheel 12 upon its inner end, to receive motion from the wheel 0 on the drivingshaft of the machine. Upon this shaft h are secured the small pulley Hand the cone-pulley F. Above the. shaft it there is journaled l,.which is provided with a pulley, H, forreceiving motion through a belt from the shaft h, and with a cone-puloperating the flier B through suitable belts.

From the cone-pulley F there passes a belt up over the cone-pulley E on the sleeve e, which has a longitudinal and transverse slot, 8. Both of the pulleys FE are slip-belt pulleys, so termed from the fact that at certain times, hereinafter explained, the belt which con= slip, the edges of belt from slipping off.

Passing through the sleeve e is the tube 6, having a slot, 8, to correspond with the one sin the sleeve 0, and which sleeve extends through the sleeve and hollow stud O to the bobbin 1), at which point there is attached to it the arm 1, to catch behind the projection d on the bobbin; also, fastened to the inner end of this tube is a pinion, k.

The two flier-heads A A are journaled in the two studs 0 O, which are boltedon top of the frame D, and these heads consist of two cone'pulleys firmly connected together by the bars 11. By imparting motion to the flier by so as to prevent the ically back and forth along the length of the belts running on the pulleys of which the flier-heads are composed, a greater speed can be obtained with safety than by other methods and by making the heads of cone-pulleys the Speed of the flier can be regulated without changing the speed of the driving-shaft.

Extending through the tube lis a rod, m, which extends into the bobbin 1) far enough to form a support for that end of the bobbin. The other end of the bobbin is supported by apin 0r stud fixed in the cross-bar g. This rod m is provided with a pin or stud to engage with the slots 8 s, so that when the slipbelt pulley E is revolved the sleeve 0, to which it is secured, gives motion to the rod m by means of the pin or stud e, which engages with the slot 8 in the sleeve. This sleeve also causes the tube 1 to revolve as the pin or Stud' 0 catches in the slots. When the tube l is revolved by the pulley E and pin 6, the arm at engages with the pin or projection on the end of the bobbin 1), and thus causes the bobbin to revolve also.

Inside of the flier-head A is pivoted the toothed wheel I, which receives its motion from the pinion k, which pinion is secured to the tube l. Secured to or forming part of this wheel 3 is the small chain-wheel i, around which wheel 2' and the one 0 on the endless screw 10 passes the endless chain c. Thescrew to, being journaled in the two flier-heads, is carried around the bobbin, and as it is carried around the screw is made to slowly revolve upon its own axis for the purpose of moving the guide'L back and forth. When the endless screw is revolved the guide L, which guides or supports the yarn, moves automatscrew, by which means the yarn is guided so as to be evenly wound upon the bobbin.

The flier receiving motion as described has a much greater speed than the pulley E, and the bobbin [1 has the same speed as the tube l and pulley E. The ditference between the speeds of the flier and the bobbin caused by having the belts run the flier much morerapidly than the bobbin is run causes the yarn to be wound on the bobbin and creates a tension or draft on the yarn, so that it is drawn into the flier and spooled as fast as it is spun. When an obstruction occurs in the sliver which prevents it from passing freely through the mechanism of the gill which regulates the size of the yarn, the belt which connects the pulleys F and E slips, and the bobbin revolves at the same or nearly the same speed as the flier until the obstruction is passed. The diflerence in speed between the bobbin and the flier also causes the endless screw to revolve by the means before described, and thus evenly wind the yarn upon the bobbin.

The nipping-rolls (shown in Fig. 2) consist of the grooved roll 2, which is rigidly secured to its shaft, and the roll .r, having a flange to work in the groove, which rollx is made removable from its shaft N, so that ditferent rolls may be used, according to the amount of tenslon necessary.
